Similar to X-ray diagnostics or photon radiation therapy, one does not feel anything of the radiation with protons itself.
Radiotherapy is a local measure. In addition, since proton therapy allows the radiation to unfold directly in the tumour, the surrounding tissue and organs are protected to the best of their ability. If a reaction – i. e. a side effect – occurs, only the irradiated body region is usually affected. This can lead to irritation of the skin or mucous membranes, which usually recede completely within two to three weeks after treatment. Sometimes, however, a kind of permanent scarring can also occur as a late consequence.
The treatment of the prostate can cause a burning sensation when urinating. However, these side effects are easy to control and disappear within a few weeks. If chemotherapy is carried out in parallel, changes in the blood count and increased irritation of the mucous membrane can also occur.
In general, fatigue, unwillingness or loss of appetite can also occur in patients. This is caused by the body’s efforts to process the rays. However, the possible side effects of proton therapy described above are very individual and depend on the place of irradiation, the individual or total dose and also on the frequency of irradiation. In addition, the radiation sensitivity is different for every person. You will be informed in detail during the initial presentation, and you will also be informed about how side effects can be avoided and, if necessary, how they can be treated. You will be monitored during the treatment. If side effects should occur, please inform your doctor or a MTRA/radiographer about them, they can be observed and countermeasures can be taken.
